Bugfixes: - slow scanning of inverted lists (#836). Features: - add basic support for 6 new metrics in CPU `IndexFlat` and `IndexHNSW` (#848); - add support for `IndexIDMap`/`IndexIDMap2` with binary indexes (#780). Misc: - throw python exception for OOM (#758); - make `DistanceComputer` available for all random access indexes; - gradually moving from `long` to `int64_t` for portability.
